Resumo

Assuming cosmic rays at ultra-high energies being of extragalactic origin we discuss propagation of cosmic iron nuclei with energies above 1019 eV from their sources to the Galaxy. In extragalactic space cosmic nuclei interact with background emissions and inevitably fragment. We analyze the fraction of iron nuclei reaching the Earth and its energy dependence on distances from cosmic ray sources. It is obtained that energies of iron nuclei can be used to find restriction on the distances from their sources.
